There are currently around three and a half million homes in England with the very least efficient type of boiler (G-rated or worse).

To address this the Government is offering up to 125,000 households £400 towards the cost of upgrading their boiler (if G-rated or equivalent or worse) to a high efficiency A-rated one or a renewable heating technology. This will help to save in the region of 140,000t CO2 per year - equivalent to taking 45,000 cars off the road.
